Application June 3, 1933, Serial No. 674,225

11 Claims. (01.123-185) of snapping a whip, and is apt to hit otheroccupants in the boat.

Therefore, an object of this invention is the provision of simple andeflicient means for preventing the inner end of the rope from leavingthe motor until lifted off, and in no case apt to fiy off and hurtoccupants of the boat, or cause operator to lose balance by reason ofsudden release of end of rope.

Another object of the invention is a novel device or adapter forattachment as a unit to the motor shaft of an outboard motor, wherebythe starting rope is detachably secured thereto,

. against accidental displacement.

A'still further object of the invention is the provision of means, in anoutboard motor ropeattaching device, for carrying a supply of theordinary brass shear pins for attaching the propeller.

, In the drawing:

Figure 1 is a view in side elevation of a device constructed inaccordance with the present invention, showing rope in position, readyfor starting motor, while 3 Figure 2 is a top plan view of the same.

Figure 3 is a vertical central sectional view of the post or adapterdevice, showing the same secured to a nut on the outer end of themotorshaft, and showing brass shear pins loosely contained inside;

Figure 4 is an enlarged view of the bottom or inner end of the adapterdevice, showing broaching to fit hexagon nut on end of motor shaft.

Figure 5 is a fragmentary view in side elevation of the propeller andpropeller shaft of an outboard motor, showing brass shear pin in place.

Referring to the drawing by numerals, 1 designates the propeller shaftof an outboard motor.

I On the outer end of shaft 1 is the propeller hub 4;

this hub is secured on said shaft by a brass shear pin 5. 2 is a nutwhich assists in securing the fly wheel 3 on motor shaft. The fly wheelis provided with the usual flange 6 having the ordinary rope-receivingnotch 7. The rope 8 extends through notch '7 and is adapted to be woundupon the fly wheel, in groove 9 (Fig. 1) under the flange 6, when it isdesired to rotate or spin the motor for the purpose of starting thesame.

The term rope is used in this specification and the appended claims in abroad sense, meaning any kind of .means that would perform the samefunction, such, for instance, as a flexible cable, etc.

My novel device comprises the post or adapter device 10, ring device 11and rope 8. The adapter device 10 comprises a hollow body 12 (Fig. 3)which has at its bottom or inner end a nut-receiving socket l3 and isinternally threaded and tapered at its top or outer end. A hollow cap 14is threaded into the outer end of the body 12 this cap is provided witha knurled flange 15,. producing an auxiliary shoulder 16, Intermediatethe ends of the body 12,, is a primary groove 1'7, which has an annularprimary shoulder 18. Between'shoulder 18 and shoulder 16 the reducedbody 12 con'stitutesan auxiliary groove 19. A set screw 20 is employedto engage nut 2 and thereby fixedly. secure the adapted device assembledwith the motor shaft, so that said post or adapter 80. device'and shaftrotate synchronously. It will be apparent that upon loosening set screwthe operator can quickly remove or lift the, adapted device. Thenut-receiving socket 13 can be made of any desired shape and size toaccommodate various types of nuts on various motors.-, The bottom orinner end of adapter may be fitted with flange or other means offastening to flywheel when nonut protrudes through. Further, the hollowstructure of the body 12, cap 14, and; the top'of nut 2 produces anadmirable compart ment or container 21, in which a supply of the brassshear pins 5 can be stored. This isa great convenience, because theoperator will have ready at hand a sufficient supplyof thepinsb.

The ring device ll comprises,a'large-primary eye 22 and a smallauxiliary eye 23. The rope 8 is suitably fastened or secured to theauxiliary eye 23. On the outer end of the rope is a grip 24. The primaryeye 22 is sufficiently large to readily pass over the top or outer endof the adapter device and then be seated in the primary groove 1'7,bearing against the shoulder 18 thereof. To start the motor, the rope iswound around the grooved portion of the fly wheel, thereby holding thering device securely in position upon the adapter device, with a portionof the rope extending through notch 7. When the rope is so positioned,the operator pulls on the grip 24 to quickly rotate the fly wheel,thereby spinning the motor; when the rope is unwound by this operation,the ring device 11 still remains upon the adapter device and usually theprimary eye is in the groove 17. However, if the primary eye 22 shouldjump over shoulder 18, it then rides in the auxiliary groove 19 againstshoulder 16. It has been found from extensive experience that the ringdevice rarely jumps out of groove 17 during the operation, but that inthose rare instances in which it does, the ring device is efiicientlykept from com ing entirely off the adapter device by the flange 15 ofthe cap 14. Hence, there are two retaining means for the ring device onthe adapter 'device, insuring against accidental displacement of theinner end of the starting rope from-off the adapter device.
